Power Steering Line/Hose: Description and Operation

Notes on Hydraulic Line With Quick-Release Coupling
1) Quick-release coupling with ID marking





Removing:
Push quick-release coupling (1) against pipe (4) (thereby relieving strain on spring (2)).
Press plastic ring (3) into quick-release coupling (1) and remove coupling (1).

Assembly:
Markings (K) on coupling (1) and pipe (4) must be flush.
Push quick-release coupling (1) onto pipe (4) until a "click" can clearly be heard.
To check that quick-release coupling (1) has been installed correctly, pull it back forcefully.

2) Quick-release coupling with indication pins





Removing:
Press plastic ring (2) into quick-release coupling (1) and remove coupling (1).

Assembly:
Push quick-release coupling (1) onto connector (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing
To check that quick-release coupling (1) has been correctly fitted, feel indication pins (4) at outside diameter of housing. When correctly seated, indication pins (4) cannot be pressed into housing.

Caution:
Coupling is not correctly engaged if both indication pins (4) fail to protrude from housing. Leakage is thus unavoidable.
